Abstract
Vibration data obtained for various rapid transit subway configurations are discussed with regard to the Washington Metropolitan Area Transit Authority (WMATA) and Toronto Transit Commission (TTC) systems. Measurement locations included the subway structure, ground surface, and at nearby buildings. The data were analyzed in 1/3 octave bands with a range of 3.15–1250 Hz. The subway configurations tested included circular rock tunnels, circular earth tunnels with steel and concrete liners, horseshoe rock tunnels, and cut‐and‐cover double box subways. Evaluation of the WMATA continuous floating slab performance characteristics are included, and comparisons are made between the continuous (WMATA Metro) and discontinuous double tie (TTC) floating slab trackbeds which represent the state‐of‐the‐art in rail transit train vibration isolation. Surface ground vibration characteristics of the WMATA Metro system are also compared with those of the TTC system.
